i stupidly took my cast off on my arm, 10 days before it was suppose to (personal reason, please dont ask why). i slid it off in the shower, my arm feels fine, a bit tender around where the fracture was, but what i am more concerned about it that there is a vein going across my hand that half way through it looks like its burst or swollen, it hurts a bit looks like a purple bruise like. should i be concerned about this or could it be swollen because the blood in my arm could of possibly been forced through it as i squeezed my arm through.. again. please dont ask why i did, i shouldn t of done it at all in the first place, but i am bit concerned now.
